摘要
文章旨在确定含有蒙脱石填料的未改性和改性环氧化合物的抗压强度和抗压应变,以及温度和老化时间对所考虑的环氧化合物机械参数的影响。研究对象包括未改性和改性粘合剂化合物。未改性环氧化合物有四种变体,包括基于双酚 A 的环氧树脂以及固化剂:三乙烯四胺和聚酰胺固化剂。含有蒙脱石填料的改性化合物也分为四种。样品在温度为 80 °C 的热室中放置 1 个月和 2 个月,在温度为 -40 °C 至 80 °C 的热震室中放置 1 个月和 2 个月。参考样品在室温 20-25 °C下进行了调制。环氧化合物样品按照 ISO 604 标准进行压缩强度测试。抗压强度受环境和温度、老化时间以及改性剂的影响。与参考环氧化合物相比,在高温或变温条件下的环氧化合物具有更高的抗压强度。气候室或热冲击室的操作会使样品比参考样品更容易变形。
Mechanical properties of unmodified and montmorillonite-modified epoxy compounds. Part I: compression test
The aim of the article was to determine the compressive strength and compressive strain of an unmodified and a modified epoxy compounds containing a montmorillonite filler, as well as to determine the effect of temperature and an aging time on the mechanical parameters of the considered epoxy compounds. The subject of the research was both the unmodified and the modified adhesive compounds. The unmodified epoxy compounds were made in four variants, which included the epoxy resins based on a bisphenol A as well as the curing agents: a triethylenetetramine and a polyamide curing agent. The modified compounds containing the montmorillonite filler, were also made in four variants. The samples were subjected in a thermal chamber at 80 °C for 1 and 2 months and in a thermal shock chamber in the temperature range from − 40 °C to 80 °C for 1 and 2 months. The reference samples were seasoned at room temperature 20–25 °C. The epoxy compounds samples were subjected to the compression strength tests in accordance with ISO 604 standard. The compressive strength is influenced by the environment and temperature, the aging time and the presence of the modifying agent. The epoxy compounds subjected at elevated or variable temperatures have higher compressive strength than the reference epoxy compounds. The operation of the climatic chamber or the thermal shock chamber makes the samples more deformable than the reference samples.
